New Class: PowerSupply

This class will represent a power supply unit with interesting characteristics:

Physical Type: S $($switching$,$ very light$)$ or T $($transformer$-$based, very heavy$)$

Voltage Type: F $($fixed $13\mathrm{.}8$vDC$)$ or V $($variable voltage, $320$vDC$)$

Current Handling: two numbers, separated by a slash, one indicating the maximum

temporary current available in amperes $($amps$),$ and another representing the $100\%$

duty cycle operating current $($i$.$e$.33/30)$

Meter Configuration: the type of meters found on the power supply:

$$ N $($no meters$)$

$$ V $($voltage meter only$)$

$$ C $($current meter only$)$

$$ B $($both voltage and current meters$)$

You must design and implement the PowerSupply class in your project. Create the constructor

and the dunder stringifier $($the thing that returns the string representation$)$ to represent a

Mount. This time, we won$$t make you create mutators, since we will not be using them. You

will still need to make accessors for the stated attributes. For the purposes of the accessors,

it will return the codes that were found in the files, as shown above $$ but your $\_\_$str$\_\_$ should

$$translate$$ those codes into plain$-$text explanations. A few static dictionaries will help with

this.

Upgrades

Remember that code you wrote in your Driver that took a frequency range and computed the

midpoint band metre value? That should now be moved into the RadioToolbox, as a function

called compute$\_$midpoint$\_$from$\_$frequency.

You need to upgrade the Radio class to accept new information. Radios must now additionally

have power supply amperage requirements $($the same type of information that a PowerSupply

has. You cannot connect a Radio to a PowerSupply if the PowerSupply doesn$$t have enough

amperage to ensure safe operation $($and$,$ for our purposes, the amperage requirement of the

Radio should be no more than $80\%$ of the $100\%$ duty cycle $($continuous$)$ amperage rating of

the power supply in order to be considered safe$).$ This isn$$t the job of the Radio to deal with $$

you$$ll see, later, how that happens. The Radio just stores the amperage required for operation

$($and already stores how it gets its power$).$ Add accessors to Radio to get the new instance

variable. As we mentioned for the PowerSupply, you can skip the mutators for this in the

Radio, too. Check the radios.txt file for details. Hint: does the $80\%$ rating have anything to do

with the Radio object, or will you put that somewhere else?

You$$ve now probably noticed that you$$re going to have the same information in PowerSupply as

in Radio $$ amperage values $$ and these will be used in determining compatibility.

There are no changes to Antenna at this time.

Data Files

You will be given a new set of data files for this assignment $$ do NOT use the ones from AS$1,$

they won$$t work. Additionally, there is a new file, powersupplies.txt$,$ that will describe the

power supplies systems:

physical$\_$type, voltage$\_$type, current$\_$handling, meter$\_$configuration, manufacturer, model identifier

Example:

S$,$F$,10/10,$N$,$SAMLEX,SEC$-1212$

The Radio data file is still radios.txt but now has records of the form
